THOMPSON, OF SAN JOSE, CALIFORNIA,ASSIGNOR T0 ANDERSON-BARN- G-ROVER MFG. 00., OF SAN JOSE, CALIFORNIA, ACORPORATION OF CALIFORNIA EXHAUST-BOX-FLOOR CONSTRUCTION Applicationfiled May 16,

My invention relates to exhaust boxes used in the canning art, and,although not limited thereto, is particularly adapted for the well knowndisk type of box.

The principal object of the invention is to provide an improved floor orbottom for exhaust boxes, which is inexpensive and simple to construct,easy to keep clean, and light in weight yet of sufficient strength andrigidity to support the interior mechanism of the box. My inventioneliminates all interior frame work in the box, the entire mechanismbeing supported directly upon the floor or bottom.

The above and other objects and advantages of the invention will befully described in the following specification, which should be readwith the understanding that the form, construction, and arrangement ofthe several parts may be varied, within the limits of the claims heretoappended, without departing from the spirit of the invention as setforth in said claims.

Reference should be had to the accompanying drawing, wherein Fig. 1 is aplan View, with the cover removed, of a portion of a disk type exhaustbox embodying a preferred form of my invention.

Fig. 2 is a section on the line 22 of Fig. 1.

Fig. 3 is a sectional detail on the line 33 of Fig. 2.

In the drawings, the reference numerals 1 designate suitable verticalsupports, or legs, to which are secured the sides 2 of the box. 3 arethe disks which form the can conveyer in the usual manner, and 4 areguides for establishing the tortuous can path. The disks 3 are suitablyinter-connected for rotation in the proper direction, preferably byhaving intermeshing teeth formed in their edges, as shown at 5 in Fig.2. This construction being well known in the art, and forming no part ofthe present invention, said intermeshing teeth have been omitted fromFig. 1 for the sake of clearness. Suitable means for driving the disks 3is indicated in Fig. 2 by a shaft 6, a pinion 7 and a gear 8 meshingwith said pinion and secured to one of the disks 3.

The bottom or floor of the box, which is an 1928. Serial No. 278,091.

essential feature of the present invention, comprises a series of raiseddeck portions 9 separated by troughs 10. I prefer to make the troughsparallel and extending lengthwise of the box, although this isimmaterial. For ease of manufacture, I prefer to make said troughsrectangular, as shown, although they may be of other shapes, and Iprefer to make the floor'in sections, welded or otherwise joinedtogether as shown at 11, and welded or otherwise joined to the sides 2.Using this constructiomthefloor can be made of comparatively light sheetmetal, and the bends can be'made quickly in a simple press. It isentirely possible, of course, to make the fioor in one piece by using amore elaborate press, but on account of the size, running six feet inwidth and from 10 to 25 feet in length, I find it more economical to usethe sectional construction as shown. I

The disks 3 are mounted directly upon the raised decks 9, by anysuitable means, as for example flanged bosses 13 in which are fixedspindles 14. the disks rotating upon said spindles and their upper endscarrying theguides 4 by means of brackets 15. I prefer to mount two rowsof disks upon each raised deck, as shown, althoughany other convenientarrangement may be adopted. The troughs 10 so stiffen the entire floorthat ample strength and rigidity are obtained even from comparativelylight sheet metal. If desired, a flat plate 16 may be placed beneath thefloor for additional stiffness, and secured to the bottoms of thetroughs by any suitable means, although the use of such additional plateis optional.

At one'position in the length of the box, a transverse drain pipe 17 issecured, by any means, not shown, to the bottom of the floor. The upperhalf of said pipe is cut away where it intersects the troughs 10, asshown in Fig.

3, and the bottoms of said troughs are similarly cut away where they areintersected by the pipe. There is thus a free opening into the pipe fromeach trough, as shown at 17 in Fig. 1, and any liquid which collects insaid troughs runs into said pipe and is carried away. More than one pipemay be used if desired, and it is preferable to make the troughs, or theentire floor, with a slight slope downward toward the pipe or pipes tofacilitate draining.

Openings are preferably provided in the sides of the box, one suchopening being shown at 18 in Fig. 2, covered by a suitable removableplate or door 19. By directing a stream of water from a hose throughsaid openings, the raised deck portions 9 and the 10 disks 3 can bewashed off, the water flowing into the troughs l and out through thedrain pipe 17. There being no interior frame Work necessary to supportthe disks, the entire box can be cleaned easily and quickly by flushing.with water as described.

I claim 2- 1. In an exhaust box, a floor comprising a sheet of metalbent to form a'raised deck and an adjacent depressed trough, and canconveying means mounted upon said deck.

2. In an exhaust box, a floor comprising a plurality of sheets of metalhaving their edge portions bent andjoined together to form raised decksseparated by a depressed trough,

i and can conveying means'mounted upon said decks.

3. In an exhaust box, a floor comprising a raised deck and, an adjacentdepressed trough, adrain intersecting said trough, and

can conveying means carried by said deck.

4. In an exhaust box, a floor comprising a sheet of metal bent to form aplurality of raised decks and adjacent depressed troughs, a drainconduit extending across and intersecting said troughs below the levelthereof, and can conveying means mounted on said decks.

5. In an exhaust box, a floor comprising a raised deck and an adjacentdepressed trough,

40 and a drain pipe extending across below said trough, the top of saidpipe and bottom of said trough being cut away to form a communicatingaperture.

6. In an exhaust box, a floor comprising a plurality of raised decks andintervening de-' pressed troughs, and can conveying means mounted uponsaid decks.

In testimony whereof I have signed my name to this specification.

ALBERT R. THOMPSON.
